Miley Cyrus Is Almost 21: Find Out What the Singer Has Planned for Her Big Birthday Weekend!

Miley Cyrus and her bleached eyebrows are ready to par-tay this weekend!

We've seen the celeb grow right in front of our eyes, and have witnessed her transformation from Disney star to the Twerking Queen, and tomorrow, Miley will celebrate her 21st birthday!

So what does a young, hot star that enjoys parading in barely there outfits and dancing with teddy bears have planned for the big weekend? Wonder no more, because E! News has the exclusive deets on how Miley will ring in her milestone birthday.

Unfortunately, it won't be all play the next couple of days, because the 2013 American Music Awards happen to fall on the same weekend as her big day.

E! News has been told that Cyrus will spend her actual birthday (Saturday, Nov. 23) rehearsing for annual awards show, so that she can give what will surely be a memorable (and highly talked-about, we're sure) performance during the actual show on Sunday night.

Once the AMAs are done—it's party time!

Miley will host a private birthday party at the theater of Beacher's Madhouse in Hollywood Roosevelt Hotel, a hot spot that the young singer often frequents. From there we can only imagine what will go down (probably a lot of dancing, sticking out of the tongue, and drinking, obvs).

"I want everyone to party like its their birffffday tomorrow," Miley tweeted.
